I went out on my first ride this year (at home) - yesterday.
A group of about 20 riders came up behind me and I decided to try drafting a bit - which was difficult as I am scared of leaving only one-two wheel lenghts between myself and the bike in front of me. So after a while I started letting myself drop behind.
So this one guy was feeling the need to blow a snot rocket. He had the kindness to move into the traffic lane so as not to grace anyone behind him, which worked nicely, until another guy produced a beautiful, visible cloud of aerosol - which I was unable to evade. Just hold your breath and pray there's no virus in it.
Yuck.
